00:00:00.000 --> 00:00:03.910 A:middle L:90%
value of sign of negative three pi over two radiance
2
00:00:03.919 --> 00:00:07.360 A:middle L:90%
. So in order to do this, we need
3
00:00:07.360 --> 00:00:10.720 A:middle L:90%
to find what that co terminal angle would be a
4
00:00:10.730 --> 00:00:13.740 A:middle L:90%
three negative three pi over two. So we're gonna
5
00:00:13.740 --> 00:00:19.000 A:middle L:90%
do that by adding negative three pie over two plus
6
00:00:19.539 --> 00:00:21.809 A:middle L:90%
two pi. We're gonna go ahead and put that
7
00:00:21.809 --> 00:00:23.300 A:middle L:90%
over one, because we're gonna have to find a
8
00:00:23.300 --> 00:00:26.539 A:middle L:90%
common denominator. So that will be negative. Three
9
00:00:26.539 --> 00:00:30.690 A:middle L:90%
pie over two because their common denominator will be too
10
00:00:31.320 --> 00:00:36.780 A:middle L:90%
. Plus four pi over two. I'll add enumerators
11
00:00:36.799 --> 00:00:39.920 A:middle L:90%
. So negative three pi plus four pi would give
12
00:00:39.920 --> 00:00:44.130 A:middle L:90%
me pie over to. So the code terminal angle
13
00:00:44.130 --> 00:00:47.770 A:middle L:90%
of negative three pi over two is pi over two
14
00:00:47.780 --> 00:00:51.259 A:middle L:90%
. So we're gonna find the sign off pi over
15
00:00:51.259 --> 00:00:53.859 A:middle L:90%
two, which would be our answer for sign of
16
00:00:53.859 --> 00:00:59.729 A:middle L:90%
negative three pi over two. So when I come
17
00:00:59.729 --> 00:01:04.540 A:middle L:90%
over here and look, that's going to be right
18
00:01:04.540 --> 00:01:11.790 A:middle L:90%
here at 90 degrees and because we're looking for our
19
00:01:11.790 --> 00:01:15.900 A:middle L:90%
sign, our sign is R y value. So
20
00:01:15.900 --> 00:01:19.269 A:middle L:90%
that is going to equal a positive one
